No.  At the time I had observed the problem with the x and xft font
backends; I currently only have a build of emacs-26 with the xft
backend and cannot reproduce the problem there either.  So I assume it
was fixed, or anyway stopped being a problem, long ago.  Thanks for
looking at the report again, and feel free to close it.
